The earliest my quick grep could find was 4.0BSD. I didn't find it in this
sense in pwb, but it was a quick grep...
xxx is used extensively in prior versions, but there it's meaning is
'placeholder' or 'don't care'. Mostly for /tmp/XXXX files, but also for
things like Jxxx handles all the jump commands or dates of the form 24 Feb
XXXX or stuff like that.
